But thanks to work led by Mark Linsenman, communications and data centers manager for ITS Infrastructure Services, and the Data Center Services team, the Michigan Academic Computing Center (MACC) now consumes less energy without compromising performance.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">&#8220;These energy-efficiency improvements will significantly reduce the carbon footprint and costs of operating power-intensive research systems,&#8221; said Brock Palen, director of Advanced Research Computing \u2013 Technology Services (ARC-TS).<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Specific upgrades include variable-speed pumps, which help deliver sufficient cooling while running slower, thus consuming less energy. Linsenman is also beginning to install \u201ccold aisle containment,\u201d an air containment technique that can improve the predictability and efficiency of the data center\u2019s cooling system by minimizing the mixing of hot and cold air. New controls and temperature sensors will automate the process to focus and maintain cold air in server rows where it is needed most.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Two new chillers have also been added. Round-the-clock operation of chillers is crucial given the considerable heat produced by so many servers in close proximity. Without chillers, temperatures would quickly rise to levels that would corrupt data and destroy hardware.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Combined with efficiencies gained by decommissioning old systems, these improvements bring the power and cooling capacity available to ARC-TS and research computing up to 1 megawatt. U-M&#8217;s research computing footprint continues to grow to use this capacity in the MACC data center. ITS is working to free up additional capacity for research computing in its ongoing effort to move ITS systems to the cloud.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Recent improvements allow the Michigan Academic Computing Center to consume less energy and reduce cost without compromising performance.<\/p>\n","protected":false},"author":7,"featured_media":7994,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_uag_custom_page_level_css":"","_umich_oidc_access":"","_monsterinsights_skip_tracking":false,"_monsterinsights_sitenote_active":false,"_monsterinsights_sitenote_note":"","_monsterinsights_sitenote_category":0,"_ef_editorial_meta_date_first-draft-date":"1523836800","_ef_editorial_meta_paragraph_assignment":"","_ef_editorial_meta_checkbox_needs-photo":"","_ef_editorial_meta_number_word-count":"","footnotes":""},"categories":[7],"tags":[85,178,270,98],"class_list":["post-7993","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-projects-services","tag-arc-ts","tag-business","tag-hardware","tag-infrastructure"],"uagb_featured_image_src":{"full":["https:\/\/michigan.it.umich.edu\/news\/wp-content\/uploads\/2018\/04\/MACC_00.jpg",600,800,false],"thumbnail":["https:\/\/michigan.it.umich.edu\/news\/wp-content\/uploads\/2018\/04\/MACC_00-75x100.jpg",75,100,true],"medium":["https:\/\/michigan.it.umich.edu\/news\/wp-content\/uploads\/2018\/04\/MACC_00-150x200.jpg",150,200,true],"medium_large":["https:\/\/michigan.it.umich.edu\/news\/wp-content\/uploads\/2018\/04\/MACC_00.jpg",600,800,false],"large":["https:\/\/michigan.it.umich.edu\/news\/wp-content\/uploads\/2018\/04\/MACC_00-525x700.jpg",450,600,true],"1536x1536":["https:\/\/michigan.it.umich.edu\/news\/wp-content\/uploads\/2018\/04\/MACC_00.jpg",600,800,false],"2048x2048":["https:\/\/michigan.it.umich.edu\/news\/wp-content\/uploads\/2018\/04\/MACC_00.jpg",600,800,false],"excerpt-thumbnail":["https:\/\/michigan.it.umich.edu\/news\/wp-content\/uploads\/2018\/04\/MACC_00-200x140.jpg",200,140,true],"themonic-thumbnail":["https:\/\/michigan.it.umich.edu\/news\/wp-content\/uploads\/2018\/04\/MACC_00-60x42.jpg",60,42,true],"ioslider-thumbnail":["https:\/\/michigan.it.umich.edu\/news\/wp-content\/uploads\/2018\/04\/MACC_00-600x300.jpg",600,300,true],"post-thumbnail":["https:\/\/michigan.it.umich.edu\/news\/wp-content\/uploads\/2018\/04\/MACC_00.jpg",600,800,false],"400x250-crop":["https:\/\/michigan.it.umich.edu\/news\/wp-content\/uploads\/2018\/04\/MACC_00.jpg",188,250,false]},"uagb_author_info":{"display_name":"Ken Caldwell","author_link":"https:\/\/michigan.it.umich.edu\/news\/author\/kencald\/"},"uagb_comment_info":0,"uagb_excerpt":"Recent improvements allow the Michigan Academic Computing Center to consume less energy and reduce cost without compromising performance.","_links":{"self":[{"href":"https:\/\/michigan.it.umich.edu\/news\/wp-json\/wp\/v2\/posts\/7993","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/michigan.it.umich.edu\/news\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/michigan.it.umich.edu\/news\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/michigan.it.umich.edu\/news\/wp-json\/wp\/v2\/users\/7"}],"replies":[{"embeddable":true,"href":"https:\/\/michigan.it.umich.edu\/news\/wp-json\/wp\/v2\/comments?post=7993"}],"version-history":[{"count":2,"href":"https:\/\/michigan.it.umich.edu\/news\/wp-json\/wp\/v2\/posts\/7993\/revisions"}],"predecessor-version":[{"id":8013,"href":"https:\/\/michigan.it.umich.edu\/news\/wp-json\/wp\/v2\/posts\/7993\/revisions\/8013"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/michigan.it.umich.edu\/news\/wp-json\/wp\/v2\/media\/7994"}],"wp:attachment":[{"href":"https:\/\/michigan.it.umich.edu\/news\/wp-json\/wp\/v2\/media?parent=7993"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/michigan.it.umich.edu\/news\/wp-json\/wp\/v2\/categories?post=7993"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/michigan.it.umich.edu\/news\/wp-json\/wp\/v2\/tags?post=7993"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
